I'm so sorry to hear of your loss. We can try to prepare ourselves for that final moment, but you never truly know how it feels until it actually happens. I lost my father to renal failure, due to different complications and I was with him in his final moments. I've lost other friends and family unexpectedly and never got the chance to properly say goodbye. This was a beautiful tribute to your mom and I wish you and your family peace and comfort in this difficult time.
